Have your armor waiting in a flat dish, downstream (a large brownie pan works well).Melt the chocolate chips and margarine together in the hot sun. Or, to speed things up, use a double boiler or microwavePour the warm wet mud down into the dry soil to make a thick clay-like substance. Let the mix begin to harden, stirring until cool enough to touch.Roll the mud into sticky balls, then through the pebbly armor until it has about a 2-3" diameter. Add more dry soil (powdered sugar) and/or wet mud (margarine) as necessary.

Keep refrigerated, uncovered, to simulate a dry environment.If you'd like your mud balls to be extra-sticky, add 1/4-cup peanut butter to the softened margarine before making your mud.
